"Is there anyone that isn't shite and doesn't cost a fortune?"
Well providing both knowledgeable customer service and a product that works to spec ALL THE TIME has a cost. Maybe, unlike the competition they also deserve a profit. So if you are used to BT/TalkTalk's silly giveaways of a few bob for next to nowt - real reliable broadband is going to come as a bit of a shock in both mind and pocket.
Its worth it just to see how both A&A and Zen can even make OpenBreach's cables whizz.
